My last (angry) moment of lucid dreaming

OK, so im no fan of george w. bush jr. This showed up a few months ago in a dream. i was in a dark bar that seemed like it was set in a time before electricity was invented. It was poorly lit with an old wise man for a tender. I started talkin about how much our world would be better off without George and his gang, when the man told me that the village was angry with what i was saying, and a mob was going to come in the tavern and kill me with pitchforks/clubs/torches! I then heard the mob bang on the door and open it. They were a bunch of older men with old suits on and pure hatred in the eyes. They wanted to get me out of there, and i took off out the oppisite exit of the place. I then woke up, and was ashamed of my cowardice. I tried VERY hard to concentrate and go back to this tavern, AND IT WORKED!! i went back into the dream, armed with a pitcher of water (dont ask no clue). i then walked in the joint with vengence on my mind. I saw the old men at a table laughing and joking. i confronted them all and they ignored me at first, so i threw the pitchers water on the table and yelled at them that i was not afraid. all they did was laugh at me, but i felt a pressence as if they were not happy i learned to do this, or confront them. the dream fades after this moment.

QUESTION: WHAT WAS WITH THE PITHCHER OF WATER, AND ME THROWING IT ON THE TABLE??? ANY THOUGHTS ARE COOL!
